Electronic device with antenna

Abstract

An electronic device with antenna provided by the invention comprises: a first metal housing having a first side edge; a second metal housing having a second side edge; first and second rotating shafts respectively connected between the first side edge and the second side edge, wherein the first and second metal housing and the first and second rotating shafts form a first closed groove hole antenna structure which has a first half-wavelength resonance modal, a first middle portion and first and second rear end portions; and a first dipolar antenna arranged in the first middle portion and having a second half-wavelength resonance modal, first and second radiation portions, wherein the first radiation portion has a first feed end and a first grounding end, the first half-wavelength resonance modal is excited by the first dipolar antenna, and the first and second metal housings are connected with the first grounding end. The electronic device with antenna has a switchable operation frequency wireless wide area network function and a radio area network or WiFi application function so as to shorten the space occupied by the antenna, and the arrangement of the antenna cannot be restricted caused by shortening the screen frame.

Description

technical field [0001] The invention belongs to the technical field of electronic products, and in particular relates to an electronic device with an antenna. Background technique [0002] Portability is an important factor when considering an electronic device with wireless communication function and / or wireless networking (wireless Internet access) function, for example, a notebook computer is a portable electronic device. [0003] figure 1 Shown is a schematic diagram of a notebook computer as an electronic device category in the prior art, including an upper cover 1 with a screen (ie, "screen", the same below), a lower cover 3 as a main body of the computer, and a cover for connecting the upper cover 1 and The rotating shaft 2 of the lower cover 3. With the development of wireless networks, the notebook computers in the prior art are also developing towards the direction of wireless network functions, and the commonly used built-in (also called built-in) antennas are r...

Problems solved by technology

However, in order to make the appearance of notebook computers more eye-catching, manufacturers of notebook computers often greatly reduce (shrink) the screen frame of the upper cover, so that the location of the antenna is greatly restricted, so the same wireless communication quality even requires Under the condition of higher wireless transmission efficiency, it is undoubtedly a challenge for the antenna designer of the notebook computer. The technical solution to be introduced below is produced under this background
